Taming the Electromagnetic Boundaries via Metasurfaces: From Theory and Fabrication to Functional Devices

Figure 5

(a) Transmission coefficients for the symmetric and asymmetric metasurface slabs. Region I shows typical asymmetric line shape of Fano resonance. Region II demonstrates the ultrasharp resonance peak induced by interelement coupling. (b) Normalized magnetic fields (Hz) at the center of these resonators. The inset shows the unit cell and the points where the magnetic fields are extracted. (c) Quality factor of a cylinder array. (d) Scattering parameters of this array. Inset shows the distribution of the electric fields at resonant frequency. Figures are reproduced from (a, b) [19] and (c, d) [63].
